A little bit of details what I'm trying to do (however IMHO it is slightly or not related to the bug):
I made one common shader for all of the meshes, with bump mapping. I'm using normal maps.
For one of the very simple meshes I don't need to use normal map, so I provided a texture 1x1 with 128,128,255 color.
However, when I'm sampling this texture and just output to the color (for sampling test) I see black pixel.
Rescaling texture to the 2x2 size solves the problem. I used .tga and .jpg formats for test with same result.
May you please check it? It' could be a Ogre bug, quite annoying, because I lost some amount of time on it.

PPS: I updated drivers up to 3/27/2009, 22.214.171.12450 - same effect.Kojack wrote:Hmm, textures as small as 2x1 work fine, but 1x1 comes out as white. Strange.
